IMPROVEMENT IN WAD-G-REASING- APPARATUS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom tt may con-cern.-

Be it known t lat I, A. C. HOBBS, o'f Bridgeport, in the county ofFaireld, and State of Connecticut, have invented certain new and usefulVImprovements in Machinery for Greasing Gun-Wads and l do hereby deel arethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, making part of thisspecication, and to the letters oi' reference marked thereon; likeletters indicating like parts wherever they occur.

To enable others skilled in the art to construct and use my invention, Iwill proceed to describe it.

l My invention consists in a novel construction of an apparatus iorgieasing gun-wads as they are cut from the sheet, and in so applying thegrease to the wads as that they shall be greased or saturated aroundtheir edge or periphery only, as hereinafter more fully explained.

` Figure l is a longitudinal vertical section,

Figure 2 is a top plan view, and

Eigure is a face view of a wad, completed.

To make my improved apparatus, I provide a metallic bed-piece, A, andform a recess or cavity, B, inv its upper face, as represented in iig.1, this cavity thus forming a cup or receptacle for the grease, orlubricating-lnaterial.

ln order to keep the grease melted, or in a fluid state, l form a cavityor passage, C, in thc raised portion of the plate A, surroundillg thecup B, into which a cury rent of steam is admitted at lone end,.fron1whence it passes around vthe cup, and escapes at the opposite side ofthesame end. at which it entered, as indicated by the dotted lines andarrows in g. 2. A

rlhrough the bottom of the cup B, I make a series of holes, and securetherein tubes D, corresponding in diameter, internally, with thediameter of the wads to be greased; these tubes D, having a seriesofhorizontal slits, a, cut in them, just above the bottom ot' the cup B,as shown in iig. l.

The cutters, consisting of a series oi' steel tubes or punches, I, aresecured in aplate, E, which rests upon the bed-plate A, over the cup B,where it is secured by a wedge, o, as shown in tig. 2, or in anysuitable manner, the punches l being placed directly over the tubes l),the two thds ibrming continiums tubes, as represented in iig. l.

To secure accuracyin this respect, the upper ends ofthe tubes D arepermitted to extend a sh'ort distance up into the plate E, where theyabut aga-inst the lower ends ofthe punches I.

These devices, thus constructed, constitute the iniprovements containedin my apparatus.

In using it, the sheet of material from which the the punches, so thatit can be fed along `for anotherv cut, and so on continuously.

These features being well known, and in common use, need not be hereinfurther described.

The operation is as follows The sheet being fed along, and thewadscontinuously or successively cut therefrom, are forced down into thetubes D, as indicated by the blue lines on the leit-handtube of tig. 1.As the wads are thus forced down, the grease runs through the slits a,and, coming in contact with the edges of the wads, greases them, oneafter another, as they pass down by the slits u', the wads being forcedout at the lower open ends ofthe tubes D.

It will be observed that the slits c are arranged in two rows, in such amanner as to break joints, the slits in one row coming opposite thespaces between the slits in the other row, so as to permit the grease toflow through lall around, and thus come in contact with the entireperiphery of the wad. y

By this arrangement, there is just enough grease used to thoroughlygrease the entire edge ci' the wad, without saturating the entire body,the greased part thus forming a ring around the outer edge of the wad,as indicated, or shown in tig. 3, the colored portion representing thegreased part, thus greasing only that part required, and effecting agreat economy of the lubricating-material, as well as of the labornecessary to perform the operation.

Having thusdescribed my invention,

Vhat I claim, is-

l. The plate A, provided with the reservoir for containing the grease,and the steam-passage C, for keeping the same warm, or in a duid state,and the perfo.

rated tubes D, when arranged to operate .substantially 'as and for thepurpose herein described.

2. The combination of the plate A, constructed as above described, withthe plate E, having the punches I securedtherein, substantially as `setforth.
